Polypropylene Fiber
Detailed Product Description
PP Fiber-Mesh
With polypropylene as raw material, this fiber appear net like
structure with many fiber monofilaments connected.
PP Fiber-Mesh
With polypropylene as its raw material, this fiber appear net like
structure with many fiber monofilaments connected.
When the fiber is put into the concrete, the horizontal structure
in fiber monofilament can be destroyed in the course of stirring
owing to friction and bubbing, and the fiber monofilament or
net-like structure will fully stretch, thus the concrete is
reinforced by a great number of polypropylene fibers.
As a new type concrete-strengthening fiber, it becomes a new
popular subject in the fiber of fiber concrete research and
application after glass and steel fiber.

APPLYING INSTRUCTION:
Length : Generally, the proper length of the fiber added into
concrete is 20 mm, and in the spray concrete is 10mm.
Ratio Design: Usually the proper amount of fiber to concrete is
0.9kg/m3 , and the water-proof layer of the bridge requires
1.35-1.8kg/m3, and the spray concrete in the tunnel is also the
same and other materials remain the same. The ratio of fiber and
concrete can be determined by tests for special purposes. The fiber
has better effects on the concrete with active compound materials,
such as silicon ash, coal powder, ground slag and zeolite powder.
Mixer Adoption: Double-axle horizontal compelling mixer is better
and self-dropping cylinder mixer can be used, too.
Mixing Process: Crushed stones, fibers and sands are put into the
mixer in succession. After stirring for two minutes, fiber will
fully spread and then add cement and water and stir normally. The
addition of materials also can be put into as usual, but the
stirring time should be properly prolonged to make fiber completely
mixed.
Stirring Time: The purpose of the stirring is to make fiber fully
spread into monofilament or the net fully spread, so generally the
stirring time is 2-3minutes after the addition of polypropylene
fiber-mess.
Packing: pp fiber for concrete ,1kg/ plastic bag , 20bags/pp woven bags.
20 FT can load pp fibre about 8 tons,
40 FT can load 16 tons,
40 HQ loads 18 tons.
